Suchomimus tenerensis
Suchomimus ("crocodile mimic") is a genus of large spinosaurid dinosaur with a crocodile-like mouth that lived 112 million years ago, during the late Aptian stage of the Cretaceous period in Africa. Unlike most giant theropods, Suchomimus had a very long, low snout and narrow jaws studded with some 100 teeth, not very sharp and curving slightly backward. The tip of the snout was enlarged and carried a "rosette" of longer teeth. The animal is reminiscent of crocodilians that eat mainly fish, such as the living gharial, a type of large crocodile with a very long, slim snout, from the region of India. Suchomimus also had a tall extension of its vertebrae which may have held up some kind of low flap, ridge or sail of skin, as seen in much more exaggerated form in Spinosaurus. Detailed study shows that the specimen of Suchomimus was a subadult about 11 meters (36 ft) in length and weighing between 2.9t and 5.2t, but scientists think that it may have grown to about 12 meters (40 ft) long, approaching the size of Tyrannosaurus. Chicago-based palaeontologist Paul Sereno and his team reported in 1998 that they had found fossils that represented about two-thirds of the skeleton of a huge meat-eater in the Tegama Bed of the Elrhaz Formation in Niger. They named the genus Suchomimus ("crocodile mimic") after the shape of the animal's head and the species tenerensis after the Ténéré Desert in which it was found. Suchomimus has been placed among the spinosaurids, a group of large predator-scavengers adapted for hunting fish and with less heavily-built skulls when compared to other similarly-sized theropods, like the tyrannosaurids. Apart from the back ridge, Suchomimus was very similar to the spinosaurid Baryonyx which also had strong forelimbs and a huge sickle-curved claw on its "thumb". And, as with Baryonyx, the claw was the first fossil part to be noticed by palaeontologists. Suchomimus was considerably larger than Baryonyx, but a few paleontologists have suggested that the latter might almost have been a juvenile of the former. It may also be a synonym of Cristatusaurus.
Sarcosuchus imperator
Sarcosuchus (pronounced /ˌsɑrkɵˈsuːkəs/, meaning 'flesh crocodile' and commonly called "SuperCroc") is an extinct genus of crocodyliform and distant relative of the crocodile that lived 112 Million years ago. It dates from the early Cretaceous Period of what is now Africa and is one of the largest giant crocodile-like reptiles that ever lived. It was almost twice as long as the modern saltwater crocodile and weighed approximately 8 to 10 tonnes. When fully mature, Sarcosuchus is believed to have been as long as a city bus (11.2–12.2 metres or 37–40 ft) and weighed up to 8 tonnes (8.75 tons). The largest living crocodilian, the saltwater crocodile, is less than two-thirds of that length (6.3 meters or 20.6 ft is the longest confirmed individual) and a small fraction of the weight (1,200 kg, or 1.3 tons). The very largest Sarcosuchus is believed to have been the oldest. Osteoderm growth rings taken from an 80% grown individual (based on comparison to largest individual found) suggest that Sarcosuchus kept growing throughout its entire 50–60 year average life span. Modern crocodiles grow at a rapid rate, reaching their adult size in about a decade, then growing more slowly afterward. Its skull alone was as big as a human adult (1.78 m, or 5 ft 10 inches). The upper jaw overlapped the lower jaw, creating an overbite. The jaws were relatively narrow (especially in juveniles). The snout comprises about 75% of the skull's length.
